B O B B I N SPECIFICATION forming part of Letters Patent No. 465,852,dated December 29, 1891.

Application filed March 21, 1891. Serial No. 385,936. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN I'IEGEMAN, of Amsterdam, in the county oflllontgomery and State of New York, have invented new and usefulImprovements in Bobbins, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and

" 1 and secured thereon at its lower edge by a exact description.

My invention relates to the construction of bobbins, and to the meansfor lifting or handling them.

My object is to produce as a new article of manufacture a bobbinconstructed from paper-pulp or analogous material, compressed to formand commingled with cement, which holds the particles together, and alsoin providing the bobbin with means for lifting it, which are normallydepressed so that the thread will not catch thereon as it is beingunwound, but which can be raised when desired to give a better hold, andalso in providing it with improved mechanism'for holding on the cover.

My invention consists in the several novel features of construction andoperation hereinafter described, and which are specifically set forth inthe claims hereunto annexed.

Itis constructed as follows, reference being had to the accompanyingdrawings, in which- Figure 1 is a side elevation of the bobbin. Fig. 2is a bottom plan thereof, showing in full and dotted lines the means fordetachably securing the lower edge of the cover thereon. Fig. 3 is avertical section of the base and cover, showing also the groove in thebase. tion of the upper end of the barrel, showing the means forhandling the bobbin.

A is the barrel of the bobbin, having a base 1 of any form desired. Thetop of the barrel is recessed vertically, as at 2, and is concaved, asat A plug (5 is secured in the recess, through which a rod t passesloosely, having aweight upon its lower end, loose in the recess, and aneye 5 upon its upper end, which normally lies in said concavity,substantially as shown in Fig. 4, all being so constructed that theoperator can insert his finger into the concavity and into the eye,raise the ring and rod until the weight comes up against the plug, andcarry the bobbin, without hand:

Fig. 4c is a vertical sectional eleva-' into the concavity, so that itwill not inter fere with the thread while it is being wound onto orunwound from the bobbin.

B is thebobbin-cover, stretchedontothe base cord 7, which passes aroundthe cover close to its lower edge, then through two holes therein andthrough coinciding holes 8 in the base, and into the circular groove 9.The ends are then tied, forming a bight, which is drawn over and aroundthe center 10 and into the notch 11 on the side of the center oppositeto the holes 8, thus drawing the cord tight, and drawing it and thecover down into a groove cut around the skirt of the base. The notch,receiving the bight of the cord, holds it so that it cannot accidentallyslip off from the center.

When I wish to remove the cover, I raise the cord out of the notch,untie the ends, and draw it out through the holes.

At 12 I show the ordinary opening in the base to receive the spindle. 1

The bobbin itself, barrel and base, I construct from paper-pulp oranalogous mate-- 8o rial, mixing it with suitable cement, andcompressing it in suitable dies to the degree of hardness desired. Thisgives me a barrel which will not crease or sliver to catch and break theyarn, and will not polish so that the yarn will slip off'from it, butwill always hold the yarn frictionally upon its alwaysfibrous surface,so that its tension is uniform.

WVhat I claim as my invention, and desire to secure by Letters Patent,is

1. A bobbin consisting of a base, and a barrel concaved and recessed inits upper end, and a weighted rod having an eye upon its outer end,fitting and adapted to slide in said recess and concavity, incombination.

2. The combination, with the bobbin and its cover, the groove around theskirt of the base, and the groove in the bottom of the base, of a cordpassed around the cover and through it and the skirt of the base, itsends tied together, and the bight of said cord passed around the centerpiece within the groove in the base.

3. A bobbin consisting of a baseand a barrel and means for carrying it,consisting of a rod inserted in the barrel and movable verticallytherein and having an eye upon its 5 upper end.

4:. A bobbin consisting of a base and a barrel eon caved in its outerend, and a verticallymovable eye normally lying in said concavity.

5. A bobbin consisting of a base, a barrel IO concaved in its upper end,and an eye in said concavity, in combination, as set forth.
